- Test the relationship between demographic variables and consumer behavior for Mobile Marketing activities
The analysis method used is the Chi-square test (χ2), with statistical hypotheses H0 and H1 and significance level α = 0.05. In case the P index (p-value) or Sig. index in SPSS has a value less than or equal to the significance level α, the hypothesis H0 is rejected and vice versa. With this testing procedure, the study can evaluate the difference in behavioral trends between demographic groups.
CHAPTER 4
RESEARCH RESULTS
During two months, 1,100 survey questionnaires were distributed to mobile phone users in the inner city of Hanoi using various methods such as direct interviews, sending via email or using questionnaires designed on the Internet. At the end of the survey, after checking and eliminating erroneous questionnaires, the study collected 858 complete questionnaires, equivalent to a rate of about 78%. In addition, the research subjects of the thesis are only people who are using mobile phones, so people who do not use mobile phones are not within the scope of the thesis, therefore, the questionnaires with the option of not using mobile phones were excluded from the scope of analysis. The number of suitable survey questionnaires included in the statistical analysis was 835.
4.1 Demographic characteristics of the sample
The structure of the survey sample is divided and statistically analyzed according to criteria such as gender, age, occupation, education level and personal income. (Detailed statistical table in Appendix 6)
- Gender structure: Of the 835 completed questionnaires, 49.8% of respondents were male, equivalent to 416 people, and 50.2% were female, equivalent to 419 people. The survey results of the study are completely consistent with the gender ratio in the population structure of Vietnam in general and Hanoi in particular (Male/Female: 49/51).
- Age structure: 36.6% of respondents are <23 years old, equivalent to 306 people. People from 23-34 years old
accounting for the highest proportion: 44.8% equivalent to 374 people, people aged 35-45 and >45 are 70 and 85 people equivalent to 8.4% and 10.2% respectively. Looking at the results of this survey, we can see that the young people - youth account for a large proportion of the total number of people participating in the survey. Meanwhile, the middle-aged people including two age groups of 35 - 45 and >45 have a low rate of participation in the survey. This is completely consistent with the reality when Mobile Marketing is identified as a Marketing service aimed at young people (people under 35 years old).
- Structure by educational level: among 835 valid responses, 541 respondents had university degrees, accounting for the highest proportion of ~ 75%, 102 had secondary school degrees, ~ 13.1%, and 93 had post-graduate degrees, ~ 11.9%.
- Occupational structure: office workers and civil servants are the group with the highest rate of participation with 39.4%, followed by students with 36.6%. Self-employed people account for 12%, retired housewives are 7.8% and other occupational groups account for 4.2%. The survey results show that the student group has the same rate as the group aged <23 at 36.6%. This shows the accuracy of the survey data. In addition, the survey results distributed by occupational criteria have a rate almost similar to the sample division rate in chapter 3. Therefore, it can be concluded that the survey data is suitable for use in analysis activities.
- Income structure: the group with income from 3 to 5 million has the highest rate with 39% of the total number of respondents. This is consistent with the income structure of Hanoi people and corresponds to the average income of the group of civil servants and office workers. Those
People with no income account for 23%, income under 3 million VND accounts for 13% and income over 5 million VND accounts for 25%.
4.2 Mobile phone usage in Hanoi inner city area
According to the survey results, most respondents said they had used the phone for more than 1 year, specifically: 68.4% used mobile phones from 4 to 10 years, 23.2% used from 1 to 3 years, 7.8% used for more than 10 years. Those who used mobile phones for less than 1 year accounted for only a very small proportion of ~ 0.6%. (Table 4.1)

The survey indexes on the time of using mobile phones of consumers in the inner city of Hanoi are very impressive for a developing country like Vietnam and also prove that Vietnamese consumers have a lot of experience using this high-tech device. Moreover, with the majority of consumers surveyed having a relatively long time of use (4-10 years), it partly proves that mobile phones have become an important and essential item in people's daily lives.
When asked about the mobile phone network they are using, 31% of respondents said they are using the network of Vietel company, 29% use the network of
of Mobifone company, 27% use Vinaphone company's network and 13% use networks of other providers such as E-VN telecom, S-fone, Beeline, Vietnammobile. (Figure 4.1).
Figure 4.1: Mobile phone network in use
Compared with the announced market share of mobile telecommunications service providers in Vietnam (Vietel: 36%, Mobifone: 29%, Vinaphone: 28%, the remaining networks: 7%), we see that the survey results do not have many differences. However, the statistics show that there is a difference in the market share of other networks because the Hanoi market is one of the two main markets of small networks, so their market share in this area will certainly be higher than that of the whole country.
According to a report by NielsenMobile (2009) [8], the number of prepaid mobile phone subscribers in Hanoi accounts for 95% of the total number of subscribers, however, the results of this survey show that the percentage of prepaid subscribers has decreased by more than 20%, only at 70.8%. On the contrary, the number of postpaid subscribers tends to increase from 5% in 2009 to 19.2%. Those who are simultaneously using both types of subscriptions account for 10%. (Table 4.2).

The above figures show the change in the psychology and consumption habits of Vietnamese consumers towards mobile telecommunications services, when the use of prepaid subscriptions and junk SIMs is replaced by the use of two types of subscriptions for different purposes and needs or switching to postpaid subscriptions to enjoy better customer care services.
In addition, the majority of respondents have an average spending level for mobile phone services from 100 to 300 thousand VND (406 ~ 48.6% of total respondents). The high spending level (> 500 thousand VND) is the spending level with the lowest number of people with only 8.4%, on the contrary, the low spending level (under 100 thousand VND) accounts for the second highest proportion among the groups of respondents with 25.4%. People with low spending levels mainly fall into the group of students and retirees/housewives - those who have little need to use or mainly use promotional SIM cards. (Table 4.3).

The statistics in Table 4.3 are similar to the percentages in the NielsenMobile survey results (2009) with 73% of mobile phone users having medium spending levels and only 13% having high spending levels.
The survey results also showed that up to 31% ~ nearly one-third of respondents said they sent more than 10 SMS messages/day, meaning that on average they sent 1 SMS message for every working hour. Those with an average SMS message volume (from 3 to 10 messages/day) accounted for 51.1% and those with a low SMS message volume (less than 3 messages/day) accounted for 17%. (Table 4.4)

Similar to sending messages, those with an average message receiving rate (from 3-10 messages/day) accounted for the highest percentage of ~ 55%, followed by those with a high number of messages (over 10 messages/day) ~ 24% and those with a low number of messages received daily (under 3 messages/day) remained at the bottom with 21%.

When comparing the data of the two result tables 4.4 and 4.5, we can see the reasonableness between the ratio of the number of messages sent and the number of messages received daily by the interview participants.
4.3 Current status of SMS advertising and Mobile Marketing
According to the interview results, in the 3 months from the time of the survey and before, 94% of respondents, equivalent to 785 people, said they received advertising messages, while only a very small percentage of 6% (only 50 people) did not receive advertising messages (Table 4.6).

The results of Table 4.6 show that consumers in the inner city of Hanoi are very familiar with advertising messages. This result is also the basis for assessing the knowledge, experience and understanding of the respondents in the interview. This is also one of the important factors determining the accuracy of the survey results.
In addition, most respondents said they had received promotional messages, but only 24% of them had ever taken the action of registering to receive promotional messages, while 76% of the remaining respondents did not register to receive promotional messages but still received promotional messages every day. This is the first sign indicating the weaknesses and shortcomings of lax management of this activity in Vietnam. (Table 4.7)

Example Illustrating a Summary of an English Text
(QC Pond's - TN, 2008)
When the following subordinate element is an adjective phrase, the grammatical relationship in that adjective phrase can be a main-subordinate relationship or an independent relationship.

Example:
(1) Tobicom - bright and healthy eyes .
(Tobicom Drug QC - TN, 2008)
(2) Samsung Plasma 50_inch PS - super sharp TV .
(QC of Samsung Company - TN, 2009)
In addition, the following subordinate element with subject-predicate cluster structure is also very common in noun phrases as subordinate clauses.
(1) Oral_B - the brand trusted by dentists .
Example:
(Oral_B Toothbrush QC - TN, 2008) b, Sentences with noun structure in outdoor commercial advertising Outdoor commercial advertising is a type of advertising that requires conceptuality.
general, that is, advertising usually represents a product or service so it is structured
Noun structures in outdoor commercial advertising often do not have quantifiers (preceding elements). The common noun structure is in the form: Noun + post-ending elements.
- The role of the subject (or the object being described) in outdoor commercial advertising is mainly proper nouns or noun phrases.
Example:
(1) Lifeboy - kills all bacteria.
(Lifeboy Soap Advertising - TN, 2008)
(2) Dr. Thanh herbal tea - detoxifies the body without worrying about getting hot.
(QC of Tan Hiep Phat Company - TN, 2009)
(3) Nestea - very cool.
(QC of Vietnam Tea Corporation - TN, 2008)
The nouns or central words in the noun phrase structure are mostly words of foreign origin, especially those of English origin. These names often create a modern look and give the impression that the products they represent are foreign goods. This is the way for manufacturers and advertisers to appeal to the foreign tastes of Vietnamese consumers.
● Adjective phrases that act as subordinate elements include two types: independent adjective phrases and main and subordinate adjective phrases. Each type is described in detail below:
The following adverbial phrase is a co-operative adjective phrase:
Example: ( 1) Hazeline - lively , natural .
(QC Hazeline Cosmetics - TN, 2008)
(2) X_men - confident , attractive .
(X_men Shampoo Ad - TN, 2009)
(3) Sunsilk - straight, natural.
(QC Sunsilk Shampoo - TN, 2008)
(4) Kinh Do mooncakes - delicious and nutritious .
(QC of Kinh Do Company - TN, 2008)
Example:
The following subordinate element is a subordinate adjective phrase:
(1) Comfort - long lasting fragrance .
(Comfort Fabric Softener QC - TN, 2009)
(2) Close_Up - fresh all day .
(Close_Up Toothpaste Ad - TN, 2008)
In the two examples above, the adjectives fragrant and fragrant are the main elements expressing the characteristics of the product, the secondary elements long-lasting and all day express the continued duration of those characteristics.
Thus, the following subcomponent has an adjective phrase structure that is quite commonly used in outdoor commercial advertising. It is the diversity and richness of the adjective phrase in the following subcomponent that creates the diversity of language in outdoor commercial advertising. The independent relationship of the adjective phrase in the following subcomponent is shown through the formal sign of “ ,” (comma) or the conjunction “and”. This helps the special sentence not to be truncated, not to cause a feeling of disappointment, when read, it still feels balanced, rhythmic, smooth and “easy to listen to”. This creates the appeal of outdoor commercial advertising.
The effect of the following adverbial phrase is often not only to emphasize the good, beautiful, and superior qualities of the advertised product but also to make outdoor commercial advertising highly persuasive.
● The verb phrase is the following subordinate element.
The following sub-elements of this type of construction are commonly seen on outdoor commercial billboards in front of stores selling popular consumer products. They have a characteristic pattern:
X + wholesale, retail + Y
In there:
X: is the name of the store, company, business. Y: are the types of products that X sells.
Example:
(1) Thu Binh - wholesale and retail of iron products, locks, door frames, paint, PU oil.
(QC of Thu Binh Store - TN, 2009)
(2) Nguyen Tung - wholesale and retail of suitcases, briefcases, bags, wallets, belts.
(QC of Nguyen Tung Store - TN, 2009)
The biggest advantage of this model is that advertisers can list many products they are selling.
In addition, a common structure of the following subordinate element is a verb phrase in the form: verb + noun/noun phrase. In which, the verb is the main element, the noun/noun phrase is the complement of the verb.
Example:
(1) Plusssz - improve health .
(QC Plusssz effervescent tablets - TN, 2008)
(2) Manna functional food - enhances resistance .
(QC of Cong Dung Company - TN, 2009)
(3) VCD Baby Einstein - intellectual development .
(VCD disc advertising - TN, 2009)
Thus, the following auxiliary elements in outdoor commercial advertising sentences have two main common types: adjective phrases and verb phrases.
2.2.2.2. About semantics
Outdoor commercial advertising is usually very brief, just one sentence, rarely has many sentences or even a paragraph of text, and that sentence has the task of conveying
convey the semantic content of the entire text. Thus, the phrase must take on the semantic weight of the entire sentence and the semantics of the entire text.
Outdoor commercial advertising, due to its concise nature, can be seen in the combination of words in phrases and sentences, which have both common and unique characteristics. The most notable unique characteristic of outdoor commercial advertising is that it is concise in presentation but still conveys relatively complete and concise information.
2.2.3. Characteristics of text on sentences in outdoor commercial advertising
Normally, outdoor commercial advertising text always aims to convey a certain main meaning. First of all, it must reveal the main idea and purpose of the advertisement. Each idea placed in the advertising text, whether expressed in several paragraphs, a line or even a word, must be very clear and distinct. In addition, the advertising text must be legal.
The content of the advertising text itself must attract the recipient, make him interested in the goods and then think about the need to buy the introduced item, use the service. If the advertising text has nothing to convince the buyer, the purpose of calling him to follow the advice of the advertisement is meaningless. Advertising texts must be diverse, meaningful and suitable for the imagination. Particularly effective are attractive advertising texts with a touch of humor.
To make a quick, strong, direct impression on the eyes of the recipient of the advertisement, the text of an outdoor commercial advertisement must have a reasonable capacity, logical structure and be considered. Advertisers often pay attention to balancing the amount of unique and normal information because they know that "absolutely new" will make it difficult for the recipient of the advertisement and will not remain in their memory. The
Sentences in outdoor commercial advertising texts are often loose in terms of text connection. Sometimes in outdoor commercial advertising texts, the advertisement consists of only a few phrases, forming separate sentences, each sentence expressing a specific feature or function of the product. Therefore, the connection between them is not tight, even seemingly disjointed, but the recipient of the advertisement can still understand the message that the advertiser wants to introduce.
Example:
(1) Treatment of joint pain and arthritis due to degeneration. Restores structure and function of articular cartilage.
Treatment of primary and secondary osteoporosis.
(QC Lubrex Medicine - TN, 2009)
(2) Converging technology. Luxury, fashion. Business class.
(Nokia E71 Ad - TN, 2009)
There are no linking words between phrases or sentences in the examples above. In fact, there is an outdoor commercial advertisement that has only one short sentence, and that sentence does the job of the entire text.
Example:
(1) LEAD - scooter of new standards.
(QC of Honda Company - TN, 2009)
(2) Another powerful assistant from Mobi 365.
(QC of Mobifone Company - TN, 2009)
In longer outdoor commercial advertising texts, with many elements in the copy, the sentences are more closely linked together.
Example:
(1) Nam Viet Bank
Receive savings deposits, deposits paid in VND, foreign currency with term.
Lending VND and foreign currency for production, business and asset investment.
Loans for car purchases, home purchases, home repairs and other consumer needs.
Providing bank guarantee money transfer services and other services.
(QC of Nam Viet Bank - TN, 2009)
(2) Bring your old products to participate in the program "Trade in old products, own new products and buy thousands of products at incredibly cheap prices".
The program is specially sponsored by 9 leading electronics and home appliance corporations from October 30, 2008.
Only at Quang Thai Electronics.
(QC of Quang Thai Store - TN, 2008) In addition, although not containing linking words, some outdoor commercial advertising texts have sentences written in a syntactic repetition style, and this syntactic repetition style plays a role in linking those sentences together. This way creates balance, rhythm, "very pleasing to the eye", making the reception of the advertisement
Outdoor commerce easier, more attractive.
Example:
(1) Naptune
10 points for quality
for health
(QC Naptune Cooking Oil - TN - 2009)
(2) Prudential
Always listening Always understanding.
(3) Converging technology. Luxury, fashion. Business class.
(QC of Prudential Company - TN, 2009)
(Nokia E71 Ad - TN, 2009) …
2.3. LANGUAGE IN OUTDOOR ADVERTISING IN VISUAL TERMS
2.3.1. Characteristics of fonts used in outdoor commercial advertising
The typeface used in outdoor commercial advertising must also contribute to conveying the advertising ideas to the recipient. It must attract everyone's attention and help them focus on reading the advertisement, highlighting the more important ideas about the advertising object.
Through the study of 422 collected outdoor commercial advertisements, it can be seen that outdoor commercial advertisements use the most printed fonts and graphic fonts. Printed fonts are used a lot because they are clear, easy to read, and easy to arrange and divide proportions in the entire context of the flat area displaying the advertisement. Graphic fonts are used, but not much, with the requirement that these graphic fonts must also be clear, easy to read, not elaborate, curvy, or confusing. To be effective, the fonts used by advertisers must ensure aesthetics.
Each typeface has its own psychological effect. Therefore, the form and size of the typeface must be harmonious and appropriate to the surface area of the advertisement and the type of product being advertised.

- Test the relationship between demographic variables and consumer behavior for Mobile Marketing activities
The analysis method used is the Chi-square test (χ2), with statistical hypotheses H0 and H1 and significance level α = 0.05. In case the P index (p-value) or Sig. index in SPSS has a value less than or equal to the significance level α, the hypothesis H0 is rejected and vice versa. With this testing procedure, the study can evaluate the difference in behavioral trends between demographic groups.
CHAPTER 4
RESEARCH RESULTS
During two months, 1,100 survey questionnaires were distributed to mobile phone users in the inner city of Hanoi using various methods such as direct interviews, sending via email or using questionnaires designed on the Internet. At the end of the survey, after checking and eliminating erroneous questionnaires, the study collected 858 complete questionnaires, equivalent to a rate of about 78%. In addition, the research subjects of the thesis are only people who are using mobile phones, so people who do not use mobile phones are not within the scope of the thesis, therefore, the questionnaires with the option of not using mobile phones were excluded from the scope of analysis. The number of suitable survey questionnaires included in the statistical analysis was 835.
4.1 Demographic characteristics of the sample
The structure of the survey sample is divided and statistically analyzed according to criteria such as gender, age, occupation, education level and personal income. (Detailed statistical table in Appendix 6)
- Gender structure: Of the 835 completed questionnaires, 49.8% of respondents were male, equivalent to 416 people, and 50.2% were female, equivalent to 419 people. The survey results of the study are completely consistent with the gender ratio in the population structure of Vietnam in general and Hanoi in particular (Male/Female: 49/51).
- Age structure: 36.6% of respondents are <23 years old, equivalent to 306 people. People from 23-34 years old
accounting for the highest proportion: 44.8% equivalent to 374 people, people aged 35-45 and >45 are 70 and 85 people equivalent to 8.4% and 10.2% respectively. Looking at the results of this survey, we can see that the young people - youth account for a large proportion of the total number of people participating in the survey. Meanwhile, the middle-aged people including two age groups of 35 - 45 and >45 have a low rate of participation in the survey. This is completely consistent with the reality when Mobile Marketing is identified as a Marketing service aimed at young people (people under 35 years old).
- Structure by educational level: among 835 valid responses, 541 respondents had university degrees, accounting for the highest proportion of ~ 75%, 102 had secondary school degrees, ~ 13.1%, and 93 had post-graduate degrees, ~ 11.9%.
- Occupational structure: office workers and civil servants are the group with the highest rate of participation with 39.4%, followed by students with 36.6%. Self-employed people account for 12%, retired housewives are 7.8% and other occupational groups account for 4.2%. The survey results show that the student group has the same rate as the group aged <23 at 36.6%. This shows the accuracy of the survey data. In addition, the survey results distributed by occupational criteria have a rate almost similar to the sample division rate in chapter 3. Therefore, it can be concluded that the survey data is suitable for use in analysis activities.
- Income structure: the group with income from 3 to 5 million has the highest rate with 39% of the total number of respondents. This is consistent with the income structure of Hanoi people and corresponds to the average income of the group of civil servants and office workers. Those
People with no income account for 23%, income under 3 million VND accounts for 13% and income over 5 million VND accounts for 25%.
4.2 Mobile phone usage in Hanoi inner city area
According to the survey results, most respondents said they had used the phone for more than 1 year, specifically: 68.4% used mobile phones from 4 to 10 years, 23.2% used from 1 to 3 years, 7.8% used for more than 10 years. Those who used mobile phones for less than 1 year accounted for only a very small proportion of ~ 0.6%. (Table 4.1)

The survey indexes on the time of using mobile phones of consumers in the inner city of Hanoi are very impressive for a developing country like Vietnam and also prove that Vietnamese consumers have a lot of experience using this high-tech device. Moreover, with the majority of consumers surveyed having a relatively long time of use (4-10 years), it partly proves that mobile phones have become an important and essential item in peoples daily lives.
When asked about the mobile phone network they are using, 31% of respondents said they are using the network of Vietel company, 29% use the network of
of Mobifone company, 27% use Vinaphone companys network and 13% use networks of other providers such as E-VN telecom, S-fone, Beeline, Vietnammobile. (Figure 4.1).
Figure 4.1: Mobile phone network in use
Compared with the announced market share of mobile telecommunications service providers in Vietnam (Vietel: 36%, Mobifone: 29%, Vinaphone: 28%, the remaining networks: 7%), we see that the survey results do not have many differences. However, the statistics show that there is a difference in the market share of other networks because the Hanoi market is one of the two main markets of small networks, so their market share in this area will certainly be higher than that of the whole country.
According to a report by NielsenMobile (2009) [8], the number of prepaid mobile phone subscribers in Hanoi accounts for 95% of the total number of subscribers, however, the results of this survey show that the percentage of prepaid subscribers has decreased by more than 20%, only at 70.8%. On the contrary, the number of postpaid subscribers tends to increase from 5% in 2009 to 19.2%. Those who are simultaneously using both types of subscriptions account for 10%. (Table 4.2).

The above figures show the change in the psychology and consumption habits of Vietnamese consumers towards mobile telecommunications services, when the use of prepaid subscriptions and junk SIMs is replaced by the use of two types of subscriptions for different purposes and needs or switching to postpaid subscriptions to enjoy better customer care services.
In addition, the majority of respondents have an average spending level for mobile phone services from 100 to 300 thousand VND (406 ~ 48.6% of total respondents). The high spending level (> 500 thousand VND) is the spending level with the lowest number of people with only 8.4%, on the contrary, the low spending level (under 100 thousand VND) accounts for the second highest proportion among the groups of respondents with 25.4%. People with low spending levels mainly fall into the group of students and retirees/housewives - those who have little need to use or mainly use promotional SIM cards. (Table 4.3).

The statistics in Table 4.3 are similar to the percentages in the NielsenMobile survey results (2009) with 73% of mobile phone users having medium spending levels and only 13% having high spending levels.
The survey results also showed that up to 31% ~ nearly one-third of respondents said they sent more than 10 SMS messages/day, meaning that on average they sent 1 SMS message for every working hour. Those with an average SMS message volume (from 3 to 10 messages/day) accounted for 51.1% and those with a low SMS message volume (less than 3 messages/day) accounted for 17%. (Table 4.4)

Similar to sending messages, those with an average message receiving rate (from 3-10 messages/day) accounted for the highest percentage of ~ 55%, followed by those with a high number of messages (over 10 messages/day) ~ 24% and those with a low number of messages received daily (under 3 messages/day) remained at the bottom with 21%.

When comparing the data of the two result tables 4.4 and 4.5, we can see the reasonableness between the ratio of the number of messages sent and the number of messages received daily by the interview participants.
4.3 Current status of SMS advertising and Mobile Marketing
According to the interview results, in the 3 months from the time of the survey and before, 94% of respondents, equivalent to 785 people, said they received advertising messages, while only a very small percentage of 6% (only 50 people) did not receive advertising messages (Table 4.6).

The results of Table 4.6 show that consumers in the inner city of Hanoi are very familiar with advertising messages. This result is also the basis for assessing the knowledge, experience and understanding of the respondents in the interview. This is also one of the important factors determining the accuracy of the survey results.
In addition, most respondents said they had received promotional messages, but only 24% of them had ever taken the action of registering to receive promotional messages, while 76% of the remaining respondents did not register to receive promotional messages but still received promotional messages every day. This is the first sign indicating the weaknesses and shortcomings of lax management of this activity in Vietnam. (Table 4.7)
